TOOL OPERATINGAND HOLDING DEVICE.

Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed April 26, 1906. serial No. 313,664.

To all whom it may concern.-

Be it known that I, WILLIAM HENERY DONNELLY, a citizen of the UnitedStates, r'esiding at Maroa, in the county of Macon and State ofIllinois, have invented certain new and useful Improvements in ToolOperating and Holding Devices; and I do hereby declare the following tobe a full, clear, and eX- act description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to new and useful improvements in tool holding andoperating devices; and my object is to provide a tool of this classwhich may be used for holding and operating various kinds of tools, suchas wrenches, drills, and the like.

Other objects and advantages will be hereinafter made clearly apparentin the specification and pointed out in the claims.

In the accompanying drawings I have shown the preferred forms of myinvention.

In said drawings, Figure 1 is a plan view of my improved tool-operatingdevice with the tool-holder removed from the socket. Fig. 2 is anenlarged detail sectional view of the upper end thereof, showing a toolseated directly in the operating device. Fig. 3 is a perspec tive viewthereof. Fig. 4 is a perspective view of the operating device, showingthe tool-holder therein and engaging a wrench. Fig. 5 is a similar viewshowing the holder engaging a different form of wrench from that shownin Fig. 4. Fig. 6 is a detail sectional view through the upper end ofthe tool-operating device, showing the tool-engaging device therein.Fig. 7 is a view of the tool-engaging device removed from the operatingdevice, and Fig. 8 is a perspective view showing the operating deviceused in'connection with the drilling appliance.

Referring to the drawings by numerals of reference, 1 indicates thehandle of my improved tool-operating device, at the upper end of whichis formed a head 2, said head having a circular opening 3 therethroughin which is seated a shank 4, said shank having a socket 5 therein andextending longitudinally therethrough. One end of the shank 4 isprovided with a ratchet-wheel 6, while the opposite end thereof isthreaded to receive a nut 7 and by which means said shank is held in thesocket 3. A shaft 8 is secured to the handle 1 in suitable bearings 9and has a latch 10 at its upper end, said latch being arranged tosuccessively engage the notches in the socket 5 is square and is adaptedto receive a bolt 13, which has a head 14 at one end thereof, while theopposite end of said bolt is threaded to receive a locking-nut 15, andthe head 14 is provided with an elongated slot 16, in which is adaptedto take the shank 17 of a tool, such as a wrench or the like, the shankbeing secured in the slot 16 by means of a locking member 18, saidlocking member having an opening therein through which passes the bolt13 and also having a slot 19, in which takes the head 14 of the bolt,the extreme outer end of the locking member engaging the shank of thewrench or the like when the bolt 13 is drawn toward said locking deviceby means of the locking-nut 15. A washer 20 is disposed between thelocking member 18 and the end of the shank 4, thereby disposing the endof the locking member 18 into firmer engagement with the shank 17 Inoperation the locking-nut 15 is loosened and the bolt 13 movedlongitudinally through the socket 5 until the slot 16 in the head 14 isbeyond the end of the locking member 18,

when the shank of the tool is inserted into the slot 16, when the nut 15is again directed inwardly on the bolt 13 and the shank of the toolsecurely locked into the slot 16 by means of the locking member 18pressing thereagainst. The tool is then ready to be applied to use, andas the operating device is provided with a ratchet said tool may bereadily rotated in either direction by changing the direction of thelatch 10 on the end of the shaft 8, thereby enabling the tool to be usedin a limited space. In some instances also the tool-holding appliancemay be dispensed with and the shank 17 of the tool inserted directlyinto the socket 5, as best shown in Figs. 2 and 3 of the drawings.

Referring more particularly to Fig. 1 of the drawings, it will be seenthat when the latch 10 is disposed as therein shown the object beingturned will be directed to the left; but should it be desired to turnthe object in the opposite direction the'handle 11 is disposed to theopposite edge of the handle 1, thereby disposing the tapered edge of thelatch 10 in the opposite direction, so that the object being turned willbe directed to the right. If, however, it is desired to direct thehandle 1 in a complete circle around the object being turned, the handle11 is disposed straight out or at right angles to the handle 1, therebylocking the ratchet-wheel rigid with the head 2, so that the objectbeing turned may be rotated in either direction at will. The latch 10can also be disposed entirely out of engagement with the ratchet-wheel 6by moving the handle 11 downwardly. The latch is normally held intoengagement with the ratchet-wheel 6 by means of a spring 21, said springbeing disposed around'the shaft 8 and between the handle 11 and thelower bearing 9.

In Fig. 8 of the drawings I have shown my improved tool-operating deviceas used in connection with a drill. In this connection a drill 22isplaced in the socket 5, said drill and tool-operating device being heldin operative position by means of a frame 23, one end of said framesupporting the object to be drilled, while the opposite end thereofforms a bearing for an adjusting-head 24, one end of said head bearingagainst the frame 23, while the opposite end thereof is provided with athreaded socket in which takes one end of a threaded bolt 25, the freeend of said bolt bearing against the drill operating mechanism andforcing the drill against the object being drilled. By turning theadjustable head 24 and holding the bolt 25 stationary the drill 22 willbe directed under pressure against the object being drilled at alltimes. An adjustable support 26 is also provided for the drill 22,whereby said drill is held from lateral movement.

I/Vhat I claim is 1. A tool securing and operating device comprising ahandle having a head at one end thereof, a shank mounted in said head, a

2. In a tool securing and operating member, the combination with anoperating-handle having a head at one end, a shank through said head,and means to rotate said shank; of a bolt seated in a socket in saidshank, a head at one end of said bolt having an elongated slot therein,a locking-nut at the opposite end of said bolt, and a locking memberdisposed on said bolt between said shank and head to engage a tool insaid slot.

8. In a tool engaging and operating member of the class describedcomprising the combination with a handle and a shank mounted in saidhandle; of a tool-engaging device comprising a bolt disposed throughsaid shank, a head at one end of said bolt having an elongated slottherein, a lockingnut at the opposite end of said bolt, a locking devicelongitudinally movable on said bolt between said head and shank, saidlocking device having a slot therein to receive said head whereby, whenthe locking-nut is disposed on said bolt, said locking device willengage the shank of a tool in said slot.

4. A tool-operating device comprising a handle having a head at one endthereof, a shank rotatably mounted in said head, said shank having asquared socket longitudie nally therethrough, a ratchet-wheel integralwith one end of said shank and threaded at its opposite end, a nutadapted to engage said threaded end and hold the shank in the head, acircular shaft rotatably mounted and longitudinally movable in bearingson said handle, the extreme upper endof said shaft being substantiallysquare and having a ta: pered face to form a latch, said latch adaptedto engage said ratchet-wheel, a controllinghandle on said shaft wherebythe shaft may be rotated to reverse the travel of said shank or to holdrigid withthe tool-handle a spring surrounding the shaft between thelower bearing and controlling-handle and means to adjust said handleupon said shaft whereby the tension of said spring may be increased ordecreased.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM HENERY DONNELLY.
